SOUTH SAN FRANCISCO, Calif., Aug. 03, 2023 (GLOBE NEWSWIRE) -- Cytokinetics, Incorporated (Nasdaq: CYTK) reported financial results for the second quarter of 2023. Net loss for the second quarter was $128.6 million, or $1.34 per share, compared to net loss for the second quarter of 2022 of $19.8 million, or $0.23 per share. Cash, cash equivalents and investments totaled $592.6 million at June 30, 2023.

“In the second quarter we made substantial progress across our pipeline, with notable advancements in the development program of aficamten, including our completing enrollment in SEQUOIA-HCM, with 282 patients, making it the largest randomized trial of an investigational therapy in HCM. We are pleased with ongoing study conduct and expect topline results from SEQUOIA-HCM by year end,” said Robert I. Blum, Cytokinetics’ President and Chief Executive Officer. “During the quarter we also started a second Phase 3 clinical trial of aficamten in obstructive HCM, MAPLE-HCM, furthered preparations for ACACIA-HCM, our Phase 3 clinical trial in non-obstructive HCM expected to start next month and began a Phase 1 study of CK-586, a cardiac myosin inhibitor, that we plan to develop for the potential treatment of heart failure with preserved ejection fraction. Finally, in the second quarter, we prioritized company activities and reduced expected operating expenses for 2023 by approximately 15 percent in order to further extend our cash runway through key corporate milestones.”

Q2 and Recent Highlights

Cardiac Muscle Programs

aficamten (cardiac myosin inhibitor)

• Completed patient enrollment in SEQUOIA-HCM (Safety, Efficacy, and Quantitative Understanding of Obstruction Impact of Aficamten in HCM), the first Phase 3 trial of aficamten in obstructive hypertrophic cardiomyopathy (HCM), enrolling a total of 282 patients.
• Announced the start of MAPLE-HCM (Metoprolol vs Aficamten in Patients with LVOT Obstruction on Exercise Capacity in HCM), the second Phase 3 clinical trial in patients with symptomatic obstructive HCM, comparing aficamten as monotherapy to metoprolol as monotherapy.

Financials

Revenues for the three and six months ended June 30, 2023 were $0.9 million and $5.5 million, respectively, compared to $89.0 million and $90.1 million for the corresponding periods in 2022. The changes in revenues are due primarily to the recognition of $87.0 million in 2022 of deferred revenues for royalties on the net sales of products containing mavacamten.

Research and development expenses for the three and six months ended June 30, 2023 increased to $83.2 million and $162.6 million, respectively, compared to $57.1 million and $103.1 million for the same periods in 2022. The changes were primarily due to increased spending for our cardiac myosin inhibition programs.

General and administrative expenses for the three months ended June 30, 2023 decreased to $39.7 million from $42.7 million from the three months ended June 30, 2022, primarily due to lower outside service spend. General and administrative expenses for the six months ended June 30, 2023 increased to $89.4 million from $75.8 million the six months ended June 30, 2022, primarily due to higher outside service spend and an increase in personnel related costs including stock-based compensation recorded during the period.

Revised 2023 Financial Guidance

The company today revised its financial guidance due to the reduction in expected operating expenses following the receipt of a CRL from the FDA regarding the New Drug Application for omecamtiv mecarbil and the discontinuation of COURAGE-ALS, the Phase 3 trial of reldesemtiv. The company anticipates operating expenses for 2023 will be in the range of $390 to $410 million, and net cash utilization will be approximately $310 to $320 million, resulting in projected savings of approximately 15% relative to forecasted spending for 2023. The company expects to end 2023 with more than $510 million, representing nearly two years of forward cash based on its 2023 projected net cash utilization.

About Cytokinetics

Cytokinetics is a late-stage, specialty cardiovascular biopharmaceutical company focused on discovering, developing and commercializing first-in-class muscle activators and next-in-class muscle inhibitors as potential treatments for debilitating diseases in which cardiac muscle performance is compromised. As a leader in muscle biology and the mechanics of muscle performance, the company is developing small molecule drug candidates specifically engineered to impact myocardial muscle function and contractility. Aficamten is a next-in-class cardiac myosin inhibitor, currently the subject of two Phase 3 clinical trials: SEQUOIA-HCM, evaluating aficamten in patients with obstructive hypertrophic cardiomyopathy (HCM), and MAPLE-HCM, evaluating aficamten as monotherapy compared to metoprolol as monotherapy in patients with obstructive HCM. ACACIA-HCM, an additional Phase 3 clinical trial of aficamten in patients with non-obstructive HCM, is expected to start soon. Cytokinetics is also developing omecamtiv mecarbil, a cardiac muscle activator in patients with heart failure. Additionally, Cytokinetics is developing CK-136, a cardiac troponin activator for the potential treatment HFrEF and other types of heart failure, such as right ventricular failure, resulting from impaired cardiac contractility, and CK-586, a cardiac myosin inhibitor with a mechanism of action distinct from aficamten for the potential treatment of HFpEF. In 2023, Cytokinetics is celebrating its 25-year history of pioneering innovation in muscle biology and related pharmacology focused to diseases of muscle dysfunction and conditions of muscle weakness.
